ScatterEffect class
Characters fly in from random offsets to their final positions.
Each character originates from a unique direction and distance, using deterministic noise for a chaotic but repeatable scatter.

Methods
-
applyCurve(
double t) → double -
Applies the effect's curve to a linear value
t(0.0–1.0).inherited -
getAnimations(
double progress, int charCount) → List< CharacterAnimation> -
Generates per-character fly-in from noise-based random directions.
override
-
getTotalDuration(
int charCount) → Duration -
Returns the total duration needed to animate all
charCountcharacters.inherited -
noise(
int index, [int offset = 0]) → double -
Returns a deterministic pseudo-random value (0.0–1.0) for the given
indexand optionaloffset.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
staggeredProgress(
double globalProgress, int index, int charCount) → double -
Computes the per-character progress for staggered animations.
inherited
-
toString(
) → String -
A string representation of this object.
